Question

identify the type of reaction for the chemical equation 2h₂o₂ → 2h₂o + o₂
double replacement
single replacement
decomposition
synthesis

Explanation:

To identify the reaction type, we analyze the chemical equation \( 2H_2O_2
ightarrow 2H_2O + O_2 \). A decomposition reaction is defined as a reaction where a single compound breaks down into two or more simpler substances. Here, hydrogen peroxide (\( H_2O_2 \)) breaks down into water (\( H_2O \)) and oxygen (\( O_2 \)), fitting the decomposition reaction definition. Double replacement involves two compounds exchanging ions, single replacement involves one element replacing another in a compound, and synthesis is combining substances into a single compound—none of these match here.

Answer:

C. Decomposition
